There is no specific cure available for shellfish poisoning, and antibiotics do not shorten the illness.

Drugs used to control diarrhea, vomiting, and stomach cramps should not be used except for bismuth (Pepto-Bismol). These drugs are referred to as antimotility drugs since they decrease stomach and intestine motion. Antimotility drugs other than bismuth preparations can worsen or lengthen the illness because the infectious agent is not expelled from the body as rapidly.

When to Seek Medical Care

Seek medical treatment immediately if the person is unable to tolerate oral fluids, if fever is present, or if other concerning symptoms develop.

For all other cases of shellfish poisoning, seek medical treatment as soon as possible.
